Personal preference, but I've no use for a DM on a bolt action hunting rifle. It's not needed, and is just something to lose or go bad. Some guys love 'em, I suppose.
Could be wrong, but it's my impression that on some rifles, the feed lips are part of the magazine, which makes the action cheaper to make, but might be a problem when you decide to re-barrel to another cartridge, or change to a fixed mag. If you really want to try a DM, I'd suggest getting a kit for a regular rifle so you can switch back.
